I have a blown 454 and I am running a
Restricter instead of a thermostat. Also
Not running an oil cooler. Water temp 130
And oil temp is 175. Should I run an even
Smaller restricter to get temps up? I am
Worried about building too much water pressure
And getting my exhaust manifolds too hot.

Those temps are fine

As stated, those temps are fine; you definitely do not want higher water temp, 100 to 110 is what you want on a blown deal.

Lose the water restrictors and get a oil thermostat.

It wouldn't kill you if the oil saw 200.

I got 185 on the oil Sunday. I was under the impression
That I needed hotter oil to burn off any condensation
That may develop especially from running aluminum
Heads. I had a few drops of water when I changed oil
Last. Sounds like oil thermostat is the ticket

Except I am not running a cooler for the oil so i guess that won't work
